MAN Truck & Bus - Nuremberg

Heat and steam generation at the MAN Truck & Bus SE engine plant in Nuremberg is currently largely based on a pulverised lignite boiler and two low-pressure natural gas boilers. In order to replace the climate-damaging fuel lignite in particular with CO2-free heat, the site managers decided to connect the plant to the local district heating network of the municipal energy supplier.

The Nuremberg district heating network is fed by highly efficient CHP heat, a biomass cogeneration plant and a waste incineration plant. In addition to the conversion of the heat supply, several optimisation measures in the local heating network were also investigated in order to achieve maximum CO2 savings.

By preparing an application for the BAFA funding programme under Module 4 "Energy Efficiency in the Economy", it was possible to obtain funding of around € 935,000 for the conversion of the heat supply and the optimisation of the local heating network at the site.

Part of the application was the preparation of a detailed savings calculation to determine the CO2 emissions saved, which were ultimately decisive for the amount of funding. Furthermore, it was necessary to prepare a savings concept (together with the infrastructure planning department (PKISP-N)) describing the complexity of the project. In addition to the application for funding under Module 4, an application was also submitted for an early start to the measures in order to be able to begin implementing the large-scale project at an early stage.

Customer benefits

Use of subsidies for CO2 savings by converting the heat supply from pulverised brown coal and natural gas to CO2-free district heating and optimisation of the local heating network at the production site.


MAN Truck & Bus SE has set itself an ambitious goal of reducing CO2 emissions by 50 % by 2025 compared to 2015. The engine plant in Nuremberg can make a major contribution to this by converting the heat supply and optimising the local heating network at the site.

After investigating several optimisation measures and preparing a detailed savings calculation (joint investigation with the MAN Infrastructure Planning Department (PKISP-N)), an application for funding according to EEW Module 4 was successfully submitted.


After the successful application, the approved funding amounts to around 935,000 euros according to the funding decision. Nothing more stands in the way of implementing the project.

Scope of services

The scope of services essentially refers to:

  • Elaboration of optimisation measures in the local heating network
  • Preparation of a detailed savings calculation
  • Preparation of a well-founded investment statement
  • Application for Module 4 "Energy Efficiency in the Economy"

I would like to thank you on behalf of MAN for an excellent performance and great support in the context of identifying savings potentials as well as in the application and preparation of the savings concept.
